That's right, they are more genetically related to a goose than a duck but are a duck in their own right.
I'll tell you how they taste soon, we took 14 boys to the gamekeeper today and I am collecting them tomorrow to be processed (packaged) by a gunsmiths in a town near hear who do that sort of thing. We've never tasted one so looking forward to that, I love duck.
We have found them lovely to keep, very fertile and make excellent mums, they aren't nervous creatures, don't run away from the dog and will eat out of my hand. We don't shut ours in at night, they roost but then we haven't had a fox or badger problem here as there are a lot of gamekeepers about. And what is nice is that they don't all look the same, they come in lots of different colours so you feel like you have lots of different varieties.
